Bakugou might react with his usual anger. He could lash out at the bullies verbally or even physically, which might make the situation worse. For example, if someone makes a snide comment, he could respond with a loud and aggressive retort.
The Genshin manga can potentially have spoilers. It might show events or details that haven't been encountered in the game yet. It's best to approach it with caution if you're worried about spoiling your game experience.
Definitely not. Bakugou is still alive and kicking in the manga. The creators have kept him around to drive the story forward and engage the readers with his dynamic personality and actions.
Bakugou might be initially shocked. He's used to Izuku calling him 'kacchan' for so long that it's become a normal part of their relationship. So, when Izuku stops, it could throw him off balance.
